For cancellations within 48 hours of the scheduled conference, but prior to the actual day of the mediation, there shall be a one (1) hour charge for a mediation that was scheduled for a half day, and a two (2) hour charge for a mediation that was scheduled for a full day. There shall be no charge for cancellations with more than forty-eight (48) hours notice. The cancellation fee time frames are also applicable to a continuance or rescheduling of the mediation. Any cancellation, continuance, or rescheduling should be done in writing, signed by all of the parties, and submitted to the mediator at the earliest convenience.
